“…In fact, iron could be insolubilized by chemical properties such as pH, and in particular, in alkaline conditions, which causes a deficiency problem such as the iron not being absorbed within phototrophic organisms [19,29,30]. Generally, the pH of seawater is affected by precipitation and water temperature and has a weak alkalinity of around 8.1 [31].…”

“…Interestingly, it has been suggested that tomato plants grown at alkaline pH can absorb more soluble iron from Fe-DTPA or Fe-EDDHA than from Fe-EDTA, and the use of Fe-DTPA is preferable due to the high price of Fe-EDDHA [19]. Furthermore, there were some trials where steel slag was combined with chelate elements like EDTA, humic acid, or fulvic acid in steelmaking slag to prevent iron oxidation [9,14].…”

Blue carbon ecosystems are crucial for carbon sequestration on a global scale. However, it is unclear how we could promote and maximize carbon sequestration. Here, we demonstrate that providing an iron source to seaweed fostered its growth through increased photosynthetic efficiency and transformed the carbon into a biomass. Firstly, we revealed that the mixture of the steel slag and DTPA eluted iron dramatically in seawater. Next, we applied the eluate of the slag-DTPA pellet to the seaweed. The results for the eluate treatment showed a 25.8% increase in the photosynthetic pigment level and a 44.9% increase in the seaweed weight. Furthermore, we confirmed no elution of potential toxic substances from the steel slag and DTPA pellet. Finally, we applied the pellet at a depth of 15 m near seaweeds and observed a 52.0% increase of carbon weight in the pellet treated group, while the non-treated group showed only a 10.3% increase for five months. This study indicated that steel slag-DTPA pellet treatment induced seaweed growth and efficiently transformed its carbon into a seaweed biomass. Thus, steel slag and its chelating agent may contribute to the promotion of sea forestation and a subsequent increase in carbon sequestration known as blue carbon.

“…As discussed above, the decrease in Fe diss may have been due to the increase of the pH of the nutrient solution. The optimal pH for Fe-EDTA (ethylenediaminetetraacetate) is within the range of 4.0–6.5; however, Fe-EDTA in a nutrient solution at pH 7.0 could become 25% insoluble [ 23 ]. A lack of Fe diss in the nutrient solution was also due to the breakdown of chelated Fe by UV light.…”

A balanced nutrient supply is essential for the healthy growth of plants in hydroponic systems. However, the commonly used electrical conductivity (EC)-based nutrient control for plant cultivation can provide amounts of nutrients that are excessive or inadequate for proper plant growth. In this study, we investigated the kinetics of major and minor nutrient uptake in a nutrient solution during the growth of tomato (Solanum lycopersicum var. cerasiforme Alef.) in a closed hydroponic system. The concentrations of major and minor ions in the nutrient solution were determined by various analytical methods including inductively coupled plasma-optical emission spectroscopy (ICP-OES), ion chromatography (IC), ion specific electrodes, and/or colorimetric methods. The concentrations of the individual nutrient ions were compared with changes in the EC. The EC of the nutrient solution varied according to the different growth stages of tomato plants. Variation in the concentrations of NO3−, SO42−, Mg2+, Ca2+, and K+ was similar to the EC variation. However, in the cases of PO43−, Na+, Cl−, dissolved Fe and Mn, Cu2+, and Zn2+, variation did not correspond with that of EC. These ions were generally depleted (to 0 mg L−1) during tomato growth, suggesting that these specific ions should be monitored individually and their supply increased. Nutrient uptake rates of major ions increased gradually at different growth stages until harvest (from < 3 mg L−1 d−1 to > 15 mg L−1 d−1). Saturation indices determined by MINEQL+ simulation and a mineral precipitation experiment demonstrated the potential for amorphous calcium phosphate precipitation, which may facilitate the abiotic adsorptive removal of dissolved Fe, dissolved Mn, Cu2+, and Zn2+.

A chelating agent helps crops to reuse as nutrients by mobilizing salts from the soil. This study was conducted to evaluate the effects of Diethylenetriamine pentaacetic acid (DTPA), N-(2-hydroxyethyl)-ethylene diaminetriacetic acid (HEDTA), and Ethylene diamine disuccininc acid (EDDS) for improving plant growth and reusing accumulated nutrients in soils of plastic film house. Two experiments were carried out of follows: i) For the incubation test, the availability of nutrients were examined for soils treated with distilled water, 1 mM of DTPA, HEDTA and EDDS solutions. ii) In the pot test, the impacts of watermelon growth response were examined by adding 0.5, 1, and 5 mM of chelating agent to soil. In incubation test, application of chelating agents increased the availability of soil nutrients in the following order : DTPA ≒ HEDTA > EDDS > distilled water. However, biomass of watermelon in pot test, tended to be highest in EDDS 1 mM. The absorption amount of N, P, and K of crop in EDDS 1 mM was similar to that of NPK treatment and K, Ca, Mg, and Fe tended to be high. Soil Electrical conductivity (EC) of 1 mM EDDS showed a 66% decrease compared to no treatment. These results showed that EDDS could be improved the watermelon growth. Further research is needed to evaluate the effects of EDDS for plant growth on field scale.
